Atlas. The meaning of the model of hydraulic rock drill of Copco Company
Atlas. The number in the model of the hydraulic rock drill of Copco Company has 4 digits, the first 2 digits indicate the impact power of the rock drill, and the last 2 digits indicate the drill rod specification used by the rock drill. For example, the COP3038 indicates that the impact power of the rock drill is 30kW, and the thread diameter of the drill rod used is 38mm. Of course, the impact power represented by the figures is only a rough range, or a power level. For example, the impact power of the COP1238 series is actually 12~18 kW, and the impact power of the COP1838 series is actually 18~22 kW. The numerical representation of the drill rod thread specification indicates an optimum
Atlas. The meaning of the model of hydraulic rock drill of Copco Company
Atlas. Copco's hydraulic rock drill model, such as COP 1838ME, is composed of 4 parts (letters or numbers), see Table 3, and the meaning of the 4 parts of the model is shown in Table 4.

Atlas.

For example, the COP3038 indicates that the impact power of the rock drill is 30kW, and the thread diameter of the drill rod used is 38mm. Of course, the impact power represented by the figures is only a rough range, or a power level. For example, the impact power of the COP1238 series is actually 12~18 kW, and the impact power of the COP1838 series is actually 18~22 kW. The drill rod thread specification indicated by the number indicates a most suitable specification, which does not mean that only a certain specification of the drill rod can be used, but also a range. The actual impact power of the rock drill and the specification range of the drill rod still need to be checked in the product manual to know exactly.
The numbers in the hydraulic rock drill model are often followed by capital English letters, such as CR,EX,HUX,HE,HF, LP,LE, ME, MUX,ME-CR, etc. The mother is the model code of the hydraulic rock drill. Those without these codes are the basic models. Those with these codes are the variants of the basic models. Variations are changes in performance parameters (such as impact energy and impact frequency) or structure relative to the basic model. The meaning of variant code is shown in Table 4.
As a mature world-famous company, Atlas. Copco hydraulic rock drill model preparation method is more scientific, but also different from other companies, unique. The letters and numbers that make up the model have a clear meaning, contain the manufacturer's information, express the main performance parameters and interface parameters of the rock drill, and express the main structural characteristics of the rock drill. Atlas. The meaning of the model of the hydraulic rock drill of Copco Company is relatively direct, without beating around the bush, and can basically let people in the industry know at a glance. It is a good model preparation method, which is worthy of our study and reference.

But there are some Atlas. The main performance parameters expressed by the model of the hydraulic rock drill of Copco Company are too different from the actual performance parameters. For example, the maximum pressure of the COP1440 hydraulic rock drill is 17.5MPa, and the rated impact power under the maximum pressure is 21 kW, which has far deviated from 14kW. There have been COP1338 hydraulic rock drills with the same parameter deviation. These two models have long been withdrawn from the market in the current Atlas. They are not found in the model series of Copco's hydraulic rock drills.
